[0030]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a perspective view showing an example of a resin molding apparatus having a spool / runner reuse function according to the present invention.

This resin molding apparatus comprises a take-out robot 3 for taking out and transferring a spool / runner of a resin molded product formed by a molding machine 1, a fixed mold 2a and a movable mold 2b of the mold machine 1. (Corresponding to the unloading means of the present invention), a material input section 4 for inputting a resin material into the molding machine 1, and a crusher 5 connected to the material input section 4. .

Of the above, the material input section 4 and the crusher 5
Has a structure as shown in FIG.

That is, in the figure, the material input section 4 includes fixed quantity supply sections 40a and 40b for performing fixed quantity supply of each of the virgin material and the master batch.
a, a mixing section 41 for mixing the virgin material discharged from the 40b and a master batch, and a short pipe section 42 for guiding the material mixed in the mixing section 41 into the molding machine 1. I have.

The crusher 5 comprises a hopper 50 and a crusher 51 having crushing means built therein, such as a rotary cutter 51a driven by a motor M. The pulverized material discharge port 52 provided at the bottom of the pulverizing section 51 is provided with a short pipe section 42 of the material input section 4, that is, a mixing section so that the pulverized material pulverized in the pulverizing section 51 can be directly supplied into the molding machine 1. 41
At an appropriate location downstream of

A nipper-shaped cutting blade 60 for cutting a spool / runner transferred by the take-out robot 3 in a procedure described later is provided at, for example, two places at an appropriate interval in the hopper section 50 of the crusher 5. Cutting device 6 provided
Is provided.

In FIG. 1, the take-out robot 3 is provided with a holding portion 31 at the tip end of an arm 30 for holding and holding, for example, a spool / runner. The unloading robot 3 is controlled so as to repeatedly execute a series of operations for taking out the spool / runner from between the pair of molds 2a and 2b and then putting the spool / runner into the hopper 50 of the crusher 5.

More specifically, in FIG. 3, one lot of resin molding work in the molding machine 1 is completed, and a set of molds 2a,
When 2b is separated, the holding unit 31 of the unloading robot 3 performs the raising / lowering operation of the arrow N1 and the horizontal movement operation of the arrow N2,
The spool / runner is taken out from between the molds 2a and 2b. In this case, the product part of the resin molded product and the spool
The runner is cut and separated in advance by a gate cutter (not shown). Next, the arm 3 of the unloading robot 3
No. 0 performs an operation of swinging along the arrow N4 and expanding and contracting along the arrow N5 after approaching the crusher 5 side along the arrow N3 direction, and throwing the spool runner into the crusher 5 side.

However, when the spool runner is charged into the crusher 5, as shown in FIG.
The runner A is controlled to be delivered to the nipper-shaped cutting blades 60 of the cutting device 6 provided in the hopper 50 of the crusher 5.

Next, the operation and operation of the resin molding apparatus having the above configuration will be described.

First, when a desired product is resin-molded by the molding machine 1, a spool / runner cut and separated by the gate cutter from the product is taken out from between the molds 2 a and 2 b by the take-out robot 3. Next, the spool runner is transferred by the procedure already described with reference to FIG. 3, and the spool runner A is disposed between the nipper-shaped cutting blades 60 of the cutting device 6 provided in the crusher 5 as shown in FIG. Is passed.

Upon receiving the spool runner A, the cutting device 6 operates the cutting blades 60, 60 at that time to cut the spool runner A. When such cutting is performed, for example, as shown in FIG. 5 (a), the spool runner A having the size of the full length L is divided into three as shown in FIG. 5 (b). It is a short dimension of L / 3. Then, the shortened spool / runner A falls into the crusher 5 and is thrown.

Therefore, as the pulverizing section 51 of the pulverizer 5,
It is not necessary to make the spool / runner A having the entire length L a size that can be subjected to the pulverizing process, and may be smaller than that, and the pulverizer 5 can be downsized.

Next, when the spool runner A is pulverized by the pulverizer 5, the pulverized material is supplied from the pulverized material discharge port 52 shown in FIG.
And is supplied into the molding machine 1.
Therefore, the spool runner A crushed by the crusher 5
It is not necessary to provide a transportation means for transporting the pulverized material in the molding machine 1.

On the other hand, from the mixing section 41, the mixed material of the virgin material and the master batch is also supplied to the molding machine 1 at a predetermined timing.
The mixture and the pulverized material of the spool runner A are sufficiently stirred and mixed by the stirring action of the rotation of the screw 10 while being heated and melted in the molding machine 1. Therefore, even if the pulverized material is supplied to the molding machine 1 without being mixed with the virgin material or the master batch, the mixing state of the pulverized material does not become insufficient. Therefore, a high quality resin molded product obtained by reusing the spool runner A can be obtained.

In the resin molding operation as described above,
Depending on the type of product, for example, color change may have to be performed. At the time of this color change, it is necessary to not only change the type of the master batch, but also, for example, clean the inside of the mixing section 41 of the material input section 4 and remove the material remaining in the mixing section 41.

In this resin molding apparatus, the pulverizer 5
Since the pulverized material pulverized in the step (a) is not put into the mixing section 41, the pulverized material which is most difficult to remove during cleaning is mixed in the mixing section 41.
There is no residual adhesion inside. Therefore, the mixing unit 4
The inside of the printer 1 can be easily cleaned, and the burden of work labor when changing types such as changing colors is reduced.

[0048] In the above embodiment, and connected downstream position than the mixing portion 41 of the material supply section 4 a grinder 5 has been so milled material spool runner A is not charged into the mixing section 41 However , the present invention is in no way limited to this.

For example, the crusher 5 may be connected above the mixing section 41 of the material input section 4. In this case, the pulverized material is put into the mixing unit 41, and cleaning of the mixing unit 41 is somewhat troublesome. However, even with such a configuration, the pulverized material of the spool / runner A pulverized by the pulverizer 5 is used. Need not be bothersomely transported to the material input unit 4 using a pneumatic transport pipe or the like, and the device configuration can be simplified.

Further, in the present invention, the pulverizer 5 may be connected and provided at a position different from the material charging section 4 provided with the mixing section 41 and the like. That is, each of the material input position of the virgin material or the master batch and the material input position of the pulverized material of the spool runner A may be individually provided at different positions.

Further, in the above embodiment, the spool / runner A to be fed into the crusher 5 is shortened by cutting the spool / runner A by the cutting device 6 provided in the crusher 5. corresponding to claim 6), in the present invention, of course it is not any specific configuration of the cutting apparatus 6, upon cleavage of the spool runner a may be configured for example as shown in FIG. 6 .

That is, the robot shown in FIG.
The arm 30 is provided with a nipper-shaped jig 31A, and the jig 31A can freely grip and cut the spool runner A (corresponding to claim 5 ). According to this configuration, after the spool runner A is transported above the crusher 5, the spool runner A is moved to the jig 31.
By being cut by A, it can be put into the hopper 50 of the crusher 5.

Accordingly, even with such a configuration, the size of the spool / runner A can be reduced, and the size of the crusher 5 can be reduced. Further, since the step of transferring the spool runner A to the cutting device 6 shown in FIG. 4 is not required, there is an advantage that the operation of inserting the spool runner A can be speeded up.

In any of the cases of FIGS. 6 and 4, the more the spool runner A is cut at a plurality of locations, the shorter the spool runner A becomes, and the smaller the crusher 5 becomes. Although it can be achieved, the number of specific cut portions is not limited.

In the above embodiment, the spool / runner A previously cut and separated from the resin molded product by the gate cutter is transferred by the take-out robot 3, but the present invention is not limited to this.

For example, as shown in FIG. 7A, the spool / runner A to which the product part B is connected may be transferred by the take-out robot 3 to a position above the crusher 5.

In such a case, for example, a shooter 20 or the like is arranged above the crusher 5 and
The connection portion (gate portion) between the spool / runner A and the product portion B may be cut by a gate cutter (not shown). Thereby, spool runner A
The product portion B separated from the crusher 5 can be dropped on the shooter 20 and supplied to a desired position, and the product portion B can be prevented from being improperly charged into the crusher 5.

Then, after the separating operation of the product portion B is completed as described above, the shooter 20 is retracted from the position above the crusher 5 as shown in FIG. What is necessary is just to drop and throw into the crusher 5.

As described above, in the present invention, it does not matter whether or not the spool / runner A transferred to the position of the crusher 5 is previously cut and separated from the product portion B, and may be any one. (Corresponds to item 4 )).

FIG. 8 is a sectional view of a main portion showing another example of a resin molding apparatus having a spool / runner reusing function according to the present invention.

This resin molding apparatus corresponds to the third aspect. Instead of a configuration in which a crusher is provided in the short pipe section 42 of the material input section 4 of the molding machine 1, a hopper 70 is connected, Runner A transferred by
Is provided with an inlet 7 for a spool / runner for allowing the molding machine 1 to be injected into the molding machine 1.

The spool / runner input port 7
A cutting device 6A provided with at least one or more cutting blades 60a for cutting the spool / runner A transported by the take-out robot 3 into short dimensions is provided at an appropriate position of the hopper 70.

In the resin molding apparatus having the above structure, the spool
The runner A is cut by the cutting device 6A into a large number of short pieces of, for example, about 3 mm.
The strips of the runner A can be supplied from the spool / runner inlet 7 into the molding machine 1.

Therefore, even in this case, an appropriate resin molding operation using the spool / runner A can be performed similarly to the case where the crusher 5 is used. In this resin molding machine,
Since a cutting device 6A which is cheaper than the crusher 5 can be used,
The manufacturing cost of the device can be further reduced. It is advantageous when the spool runner A has a relatively small size and a shape that can be easily cut into a short shape of about 3 mm.

In the configuration shown in FIG. 8, the cutting device 6A is provided in the hopper 70 forming the inlet 7 for the spool / runner. However, the present invention is not limited to this. Spool by cutting
The runner A may be cut into a short shape. In this case, it is preferable to provide a large number of jigs 31a for cutting the spool / runner A.

Further, in the present invention, it is not necessary to resupply the entire amount of the spool / runner A obtained with the resin molding into the molding machine 1.

In this type of resin molding operation, if the mixing ratio of the spool / runner in the resin molding material increases, the quality of the resin molded product tends to deteriorate. Therefore, as a measure to avoid this, for example, when the spool runner A is taken out by the take-out robot 3, the spool runner A is crushed only once out of a predetermined number of times such as twice or three times. (Or 7 for sprue and runner)
It may be made to throw into.

In the above example, the example in which the molding machine is provided with a mixing section for mixing the virgin material and the masterbatch on the molding machine side has been described. The present invention is not limited to this, and can be applied to a type in which a mixing machine is installed in a place different from the molding machine and the mixed material is transported from the mixing machine to the molding machine by a method such as pneumatic transportation.

FIG. 9 shows an example of such a type of resin molding apparatus.

That is, a transport nozzle for pneumatically transporting the mixture is provided below the mixing section 7c of the mixer 7 provided with the quantitative supply sections 7a and 7b for performing the quantitative supply of the virgin material and the master batch. The transport nozzle 7d is connected to a material receiving pipe 9a of a material input hopper 9 provided on the molding machine 1 side, and a suction pipe 9c of the material input hopper 9 is connected to a blower 8. For this reason, the mixed material determined by the mixer 7 is pneumatically transported from the transport nozzle 7d to the material input hopper 9 by suction driving of the blower 8, and the material discharge damper 9b is opened as appropriate to be input into the molding machine 1. Is done.

The molding machine 1 has a material input hopper 9
A crusher 5 having a built-in rotary cutter 51a is provided, and a spool
A cutting device 6 provided with a gripper (chuck) 61 of the runner A and a nipper-shaped cutting blade 60a is provided. Here, the cutting device 6 uses the three motors Mx, My, and Mz to move the gripper 61 of the spool / runner A.
Since the robot can be freely moved in the x, y, and z axis directions, the spool robot taken out by the take-out robot 3
The runner A can be cut by moving the cutting blade 60a in a three-dimensional direction while being held by the holding portion 61, so that the cut sprue / runner A can be cut into the material of the material input hopper 9. The molding machine 1 passes through the pulverized material discharge port 52 together with the mixed material discharged from the discharge damper 9b.
Is introduced into the screw 10. In this case, when the spool runner is cut into a size of about 3 mm, that is, a pellet size, the grinding step can be omitted.

In addition to the above, according to the present invention, it is not always necessary that both the spool and the runner are always integrally processed. For example, only the spool or only the runner is put into the crusher 5 for processing. Even in such a case, it belongs to the technical scope of the present invention.

[0073]

As will be understood from the above description, according to the resin molding apparatus having the function of reusing the spool runner according to the present invention described in claims 1 to 6 , the resin is pulverized by a pulverizer or Since the spool / runner that has been cut into short dimensions by the cutting device can be supplied to the molding machine as it is, unlike the conventional method, a transport device such as a pneumatic transport pipe is used to transport the crushed material of the spool / runner crushed by the crusher. There is no need to use and transport.

As a result, the structure of the entire apparatus can be reduced in size and simplified, the manufacturing cost can be reduced, and the necessity of cleaning the inside of the pneumatic transport pipe when changing the type of resin is eliminated. The special effect that can also be achieved is obtained.

In particular, according to the second aspect of the present invention,
Since the pulverized material of the spool / runner is not supplied to the mixing section of the material input section, the cleaning of the mixing section at the time of changing the type is facilitated, and the advantage that the work labor at the time of changing the type is further reduced can be obtained.

According to the third aspect of the present invention,
Since the spool runner can be cut and shortened before the spool runner is put into the crusher, the size of the crusher for receiving and crushing the spool runner can be reduced accordingly, further improving the apparatus. The advantage of miniaturization can be obtained.

Further, according to the present invention as set forth in claim 5 ,
Since the spool / runner can be cut by the nipper-shaped jig of the take-out means for holding the spool / runner, the cutting process can be performed quickly, and the crusher or the spool / runner can be cut.
The operation of inserting the spool / runner into the inlet for the runner can be sped up, and the effect of improving work efficiency can be obtained.

[0078] According to the present invention described in claim 6, received with the spool runner gripping means, since cutting the receipt was spooled runner cutting means to cut the spool runner to any size This has the advantage that the virgin pellets can be recycled in substantially the same shape as the virgin pellets.
